    modalDialog: Do not sync display here
    
    This gdk_display_sync() call was added in commit a40daa3c22 so the alt-f2
    dialog is able to spawn commands that trigger grabs on startup (eg. xmag/
    xkill).
    
    This seems worthwhile to do only on the X11 backend, and handling it in
    mutter backend code seems cleaner.
